1. numbers

   • 123

2. algebra

   • pronumerals
     • x,y,z
       • y x 2=2y
     • like terms
       • 2y, 3y
       • terms with the same pronumeral
       • like terms can be added like normal numbers
         • eg. 2y+6y=8y
   • indices
   • simplify-to make a sum shorter or simpler. to take away as many signs (+-ect.) as possible
   • evaluate-to look over a sum and answer it
   • expand-the opposite of simplify, to make the sum longer, to insert all needed signs
   • coefficient
   • powers-2 to the power of 4. (2 with a little 4 in the right hand corner), you have to multiply that number by itself that many times. eg 2 to the power of 4=2x2x2x2=16
   • abbreviation-to make a sum shorter
   • consecutive-numbers that come in order eg. 1,2,3
   • variable
   • substitution
   • quotient
   • expression-the sum

3. adition, subtraction, multiplication, division

   • you can add, subract, multiply and divide like terms as normal
   • negative and positive numbers
     • negative+negavtive=positive positive+postive=postive negavtive+positve=negative positive+negavtive=negavtive
       • goes for addition, subtraction, multiplication and division
